CORN AND COB CRUSHER.

Specification of Letters lPatent No. 28,571, dated June 5, 1860.

To all whom it may concern;

Be it known that I, AMos GLovER, of Powhatan Point, in the county of Belmont and State of Ohlo, have invented a new and useful machine for reducing corn in the ear and corncobs to meal, called the Millstone corn crusher, and also a new and improved method of combining crushers with millstones, and do hereby declare that the following is a full and clear description of the same, reference being had to the annexed drawings, making a part of this specification, in which Figure 1 is a sectional view of the machine and millstone; Fig. 2, the concave with its belongings viewed from beneath; Fig. 3, the convex with its belongings and attachments viewed from above.

The letter a designates the openings in the top of the machine at which that to be ground or crushed enters; b the parts by which the concave will be fastened; c the teeth in concave; d the teeth in convex; e the raised parts of the concave to hold fast the arms f of bearing 9, m, the convex (or runner) 0 the concave (or shell) 79 the corrugated part of convex; i the corrugated part of concave; j the receiving spaces (or enlargements); la the points at which those spaces terminate; Z the knocker m the driver; 3) the mill stone, and s the eye of the stone;

The receiving spaces (j) are the parts included. between the irregular inside surface of the concave (0) and regular circles struck on the inmost points of that surface and are designed to admit the ear or cob into the machine before the revolving teeth (d) catch it thereby enabling it to enter though the teeth should revolve ever so rapidly Thesespaces (j) diminish from a to j in the same ratiothat an ordinary ear of corn diminishes from butt to point; from y' to it they diminish faster by which faster di- .minuti0n and their diminution in the direction in which the convex (n) revolves the ear or cob is brought in contact with and is caught up by the teeth cl and carried around till it meets the teeth 0, where it is .crushed, when it drops between the corrugated surfaces (It and 2') where it is crushed fine enough to pass between the stones. By a circular arrangement of the teeth 0 while the teeth d occupy nearly or quite a perpendicular arrangement the ear or cob is crushed gradually which equalizes the resistance. The knocker (Z), (a winged continuation of the shaft of the convex) (n), shakes the hopper. The machine occupies the eye (8) of the stone (p) and the ends of the driver (m) penetrate the walls of the eye (8) hence the convex revolves with the stone.-

The working machines will be constructed with one or more receiving spaces (j) as they are designed to attach to stones grinding with greater or less rapidity, each construction requiring a different arrangement of teeth. The accompanying drawings represent'a machine with two receiving spaces (j) 'and a corresponding arrangement of teeth, and designed to work 'with stones running to the right; to work with stones running to the left the necessary parts will be reversed.

What I claim as my invention and desire to secure by Letters Patent is-- 1. The construction of the concave (0) with one or more receiving spaces (j).

2. Combining crushers with mill stones by means of the driver (m) substantially as, and for the purposes, set forth in this specification.

AMOS GLOVER.
